Title: Heat exchanging device
Inventor: GOTO TADASHI
IPC: F28D7/16
Filed: 1984-07-20
Abstract: PURPOSE:To exchange heat by flowing both primary and secondary fluids by means of the driving of a pump on one fluid side by a method wherein an electromagnetic flow coupler is established between the primary and secondary fluids by applying magnetic field on the primary and secondary flow passages, the cross-sections of both of which are formed in an annular flow passage by arranging the primary flow passages and the secondary flow passages alternately. CONSTITUTION:An annular flow passage 42 is formed by arranging an inner tube 41 at the center of a cylindrical outer tube 40. A magnetic circuit is formed by axially arranging cylindrical magnets 43 onto the outer periphery of the outer tube 40 and by arranging a bar-shaped iron core 44 in the interior of the cylindrical tube 41. The flow passage 42 is divided by partition plates 45 into a plurality of primary and secondary flow passages 47 and 46 arranged alternately. When the secondary fluid forming ascending flows 52 is flowed in the secondary flow passages 46 by means of a secondary pump 8, the electric currents proportional to the flow speed of the secondary fluid are generated within the flow passage 46 portions in the annular flow passage, resulting in forming a loop electric current 63. Electrically conductive fluid in the flow passages 47 generates the fluidizing force, the direction of which is opposite to the moving direction of the secondary flow and which causes to form descending flows 60 by receiving the electric current 63 in the magnetic fluxes 62. The fluidizing forces generated in the flow passages 47 are compounded into the total pumping force of the primary fluid 61.

Title: Method and device for selecting null requirement
Inventor: RIBETSUKA ERU SUTAAMU
IPC: G06F15/16
Filed: 1989-06-14
Abstract: PURPOSE: To prevent a processor bus from being overloaded by sending only invalidation corresponding to a memory address present inside the cache of a processor to a private processor bus. CONSTITUTION: When a write transaction is detected, a memory interface device 24 sends the address of write access through an invalidation bus 46 to a cache controller 22. The cache controller 22 inquires of a backup cache tag storage 42 and the copy 40 of a primary cache tag storage about which of the primary cache tag storage 44 and the backup cache tag storage 42 a location included in the write transaction is present in. The memory interface device 24 outputs the invalidation onto the processor bus 30 when the location of the write access is present in one of them and the processor bus 30 is left in a free state when it is not present. Thus, the reduction of system efficiency due to excessive invalidate traffic is prevented.
